With a 74 type on your licence about the only two serious options are BA or Virgin. BA are fine if you don't mind working a 7 on 3 off 7 on 4 off shift and being treated like dirt. Virgin are a far better company to work for , and after all the RR Classics at LGW are all ex ANZ anyway so you'd be on familiar territory. If you are interested drop them a CV at: Arrivals, Virgin Atlantic Airways, Griffin House, 135 High Street, Crawley, RH10 1DQ not sure if there are any jobs at the mo but with the fleet expanding like it is currently you might be in luck
Good Luck!
